American-Type Pad-Mounted Transformer – 12kV/10kV Outdoor Compact Substation (ZGS Series) for Urban and Industrial Power Distribution
The American-type pad-mounted transformer is a highly efficient and compact pre-installed substation designed for 12kV (10kV) three-phase AC power systems. This unit integrates the transformer body, high-voltage load switches, and fuses into a single oil-filled tank, significantly reducing its footprint compared to traditional substations. Engineered for outdoor reliability, it features a fully enclosed, weather-resistant green steel shell with a dedicated low-voltage compartment for safe and easy operation. Equipped with advanced cooling radiators for natural oil circulation and clear safety warning labels, the ZGS series is the ideal choice for residential neighborhoods, commercial centers, and industrial parks requiring a secure and aesthetically integrated power solution.
American-Type Pad-Mounted Transformer (ZGS Series Compact Substation)
Product Overview
The American-type pad-mounted transformer is a highly efficient and compact pre-installed substation designed for 12kV (10kV) three-phase AC power systems. This unit represents an integrated power distribution solution where the transformer body, high-voltage load switches, and protective fuses are housed within a single oil-filled tank. By combining these components, the ZGS series significantly reduces the required installation footprint compared to traditional substations, making it an ideal choice for space-constrained urban and industrial environments.
